Abstract: FIELD: civil engineering, mining industry, mechanical engineering. SUBSTANCE: vibrator has housing with fitted-in drive and two flyweights rotating in synchronism opposite to each other around cylindrical spools fixed on housing and provided with seats on surface connected by channels with pressure and drain main lines. Each flyweight has inner ring spaces and channels open to spool seat side and through diametric hole with unbalance weight fitted in and made in form of piston with two-sided stepped rods and closed by covers forming stepped working cylinders at both sides, and hydraulic accumulator. Working cylinder space is coupled through channel with ring space and, depending on angular position of channel, is connected through seat either with pressure main line, or through seat with drain main line. Simultaneously, working cylinder space is placed in communication through channel, ring space and channel with drain through spool seat, or with spool ring groove constantly connected with pressure main line. Every half a revolution of flyweight, direction of working liquid in cylinders changes into opposite one. Under action of working liquid pressure, unbalance weights are displaced over preset trajectory: being in extreme position they move over arc of circumference, then quickly change their position into other extreme position. This occurs twice a revolution. Unbalance weights remain always in one half of circle, thus creating disturbing force directed to one side. EFFECT: enlarged operating capabilities. 2 dwg

Filed: 2010-07-28
Granted: 2015-12-17
Abstract: A power supply includes two or more input waveforms being shaped or selected so that after being separately level-shifted and rectified, their additive combination results in a DC output waveform with substantially no ripple. The power supply may comprise a waveform generator, a level conversion stage for step up or down conversion, a rectification stage, and a combiner. The waveform generator may generate complementary waveforms, preferably identical but phase offset from each other, such that after the complementary waveforms are level-converted, rectified and additively combined their sum will be constant, thus requiring no or minimal smoothing for generation of a DC output waveform. The level conversion may be carried out using transformers or switched capacitor circuits. Feedback from the DC output waveform may be used to adjust the characteristics of the input waveforms.
